The CY621472G30-45ZSXIT: RoHS3 compliance is confirmed, which simplifies EU and global regulatory acceptance without a waiver or exemption review.
Memory density and access timing
Organised as 256K x 16 bits, this 4Mbit asynchronous SRAM provides a 16-bit-wide data bus that matches many embedded processor and FPGA memory interfaces without external byte packing. The 45 ns access time and 45 ns write cycle time (word/page) set the bus timing budget — the processor's memory controller must accommodate this window for read and write operations without wait states if the clock period allows.
Supply voltage and temperature grade
The wide range allows the same part to serve across different supply domains without a separate regulator.
Supplied on Tape & Reel (TR) with Cut Tape (CT) option, the packaging supports automated pick-and-place assembly and reel-fed production lines. Store the reels in a dry environment per JEDEC moisture sensitivity level handling.
